You're getting these from eBay aren't you? Somebody bought me an eBay laminated stave as a gift once. I could peel the backing away from the belly with so little effort that it convinced me to never try and skip doing the work myself again.
Either write to the guy selling it and make sure he tells you exactly what he used to glue the laminate up, or do what all these experienced people are telling you (sigh - haven't we been here before?) and grab some cheap boards, some decent glue and make 5 times the number of staves you could for the same price.
